Directing the Mobility of Guest Molecules in Nanoporous Materials by Linearly Polarized Light

open access: yesAdvanced Science, EarlyView.
The polarization of light is introduced as a further parameter to dynamically and reversibly control the properties of a photoresponsive nanoporous material. It was used to control the mobility of the guest molecules in the pores of a metal–organic framework.

Research on Optimization of Flow Field and Combustion Performance in Boilers With Combined Near‐Wall Air Supply Systems

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the pulverized coal boiler industry, reducing NOx emissions has become a critical objective. Although low‐NOx combustion technologies are effective, they may lead to localized high‐temperature corrosion. To address this issue, near‐wall air supply technology has been introduced, which involves injecting an appropriate amount of air near the

Numerical simulation of the natural fragmentation of explosively loaded thick walled cylinders

open access: yesDefence Technology, 2014
The ability to predict the natural fragmentation of an explosively loaded metal casing would represent a significant achievement. Physically-based material models permit the use of small scale laboratory tests to characterise and validate their ...

Predicting near-term, out-of-sample fish passage, guidance, and movement across diverse river environments by cognitively relating momentary behavioral decisions to multiscale memories of past hydrodynamic experiences

open access: yesFrontiers in Ecology and Evolution, 2023
Predicting the behavior of individuals acting under their own motivation is a challenge shared across multiple scientific fields, from economic to ecological systems.

Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

NP-completeness of the Eulerian walk problem for a multiple graph

open access: yesМоделирование и анализ информационных систем
In this paper, we study undirected multiple graphs of any natural multiplicity $k>1$. There are edges of three types: ordinary edges, multiple edges and multi-edges. Each edge of the last two types is a union of $k$ linked edges, which connect 2 or $(k+1)

Fast Models of Hydrocarbon Migration Paths and Pressure Depletion Based on Complex Analysis Methods (CAM): Mini-Review and Verification

open access: yesFluids, 2020
A recently developed code to model hydrocarbon migration and convective time of flight makes use of complex analysis methods (CAM) paired with Eulerian particle tracking.

Finite Element Modeling of a Thermoplastic Polyurethane Ball for Rolling Seismic Isolation

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The Elastomeric‐Ball Pendulum (EBP) system, which consists of an elastomeric ball rolling on a spherical concrete surface, has been proposed as an isolation system for lightweight structures. Experimental tests have shown that the mechanics of such a rolling ball are remarkably complicated because the vertical load changes the shape of the ...
